There is more to shutter count than just the shutter such as the whole mirror mech. and the numerous buttons that get worn out etc. Shutter replacement itself is typically $200-$350ish. It's similar to asking how many miles are on a used car-you wouldn't probably be a smart buyer if you bought a used car without asking that would you?

More than just the cost is the inconvenience and risk associated with a shutter that dies gradually instead of suddenly and affects many photos to greater or lesser degrees. When my 1Ds2 shutter played up in an obvious way I was peeved with the camera but then I found evidence of the problem starting several months earlier and I was peeved with myself for not seeing it earlier while it was still well within warranty. Two shutters and a circuit board later it is much better but that took a total of about 20 weeks without the camera spread over three services.

Changing the shutter on a camera is like changing the tires on a car. I personally don't know why folks make such a big deal of it. Yes, there is a moderate fee, but from the amount of usage you'll get out of the camera, the cost is low.

I just had my 1 D mark III's shutter replaced last month before I sold it. It cost me $263.17 from Canon Service Center in Jamesburg, N.J. with my CPS Gold 30% discount. I'm sure the newer bodies are the same or slightly higher.
